Former President Donald Trump and Vice President Kamala Harris will face off tonight in Philadelphia in their first televised debatewith the stakes high as the latest polls show a derby between the two with no clear winner.

When Kamala Harris and Donald Trump share the debate stage Tuesday night, voters will have their first and possibly only chance to see both candidates side-by-side in a race that only started about seven weeks ago when President Joe Biden dropped out of the presidential race.

Polls have highlighted the economy as the main concern of Americans, which will also determine the direction of their vote.

Trump’s tariff policy, according to economic analysts, will impose dramatically higher import taxes on goods brought into the country’s ports from abroad. This could increase revenue for the government, but will lead to an increase in goods and services for citizens.

Trump is promising more oil production, a key cost for many businesses, to drive down prices — but there’s an open question about whether he could pull that off. The United States already pumps more oil than any other country in history.

In addition, the unprecedented crackdown on immigration that Trump has promised if he returns to the White House could also lead to higher inflationeconomists say, despite Trump recently claiming that prices will “fall dramatically and quickly.”

On the other hand, Harris’ proposed policies may increase inflation.

His proposed first home tax credit and tripling of the child tax credit for newborns could save consumers more money to spend on goods and services, but also could raise their prices.

Harris has also proposed a plan that her staff says will secure 3 million homes. The issue is timing: If the first-home credit comes into effect before more homes become available, it could cause house prices to rise.

At the same time the two candidates have different approaches to how the Fed, the independent central bank charged with controlling inflation, should deal with it. Harris defends her independence in decision-making while Trump suggested the president should have influence.

How will Trump deal with Kamala Harris?

In recent days, Donald Trump’s advisers have been preparing the former president on how to respond to potentially dangerous comments from Vice President Kamala Harris.

Trump’s staff has advised him not to express irritation or respond if Harris tries to drag him into such a situation, at least not verbally. Some associates suggested that it would be better for him to respond with facial expressions, rather than verbal attacks.

Trump’s team is acutely aware of their candidate’s temperament and how his often aggressive behavior will come across to a woman.

Asked whether there would be a “change in tone” compared to how Trump approached his debate with Biden, former congresswoman Tulsi Gabbard, who is helping Trump prepare for the debate, argued that the Trump would not speak to Harris “any differently than he would speak to a man.”

But many Republicans have expressed concern, noting that Trump should refrain from personal attacks. Trump is known for the brash, even vulgar way he sometimes talks about women.

Harris’ weapons against Trump

Vice President Kamala Harris is expected to highlight women’s reproductive rights and take on former President Donald Trump over his vague messages on abortion.

Democrats raised the abortion issue before November, seeing it as a major political issue that could sway moderate voters — especially women — to turn against Trump by linking the abortion ban to his policies.

Recent CNN polls have shown Harris looking to build on the former president’s lead Joe Biden on abortion and reproductive rights management, with women in key battleground states giving them a 27% lead.

He is expected to step up efforts to tie Trump to abortion bans in the debate, especially after Trump said he would vote against a measure in his home state of Florida that would have made abortion legal up to the point of viability. many experts believe it is around 23 or 24 weeks pregnant.

That would leave in place the state’s six-week ban, which Trump has publicly said he disagrees with and called “too short.”

Harris’ campaign also recently embarked on a reproductive rights tour, starting in Florida where abortion is a major issue. It is expected to include at least 50 stops across the country.

Hillary Clinton’s advice

While in Pittsburgh over the weekend to prepare for the debate, the vice president sought advice from a woman who had faced the former president: Hillary Clinton.

The two women spoke on the phone over the weekend with Kamala Harris.

Clinton has told people close to her that looking back on her own experience debating Trump in 2016, “his bait is self-destruction,” and it’s one of the best things the vice president could do tonight.

Clinton said, for example, that she thinks one of the worst moments of the Trump debate eight years ago was when he tried to attack Clinton by telling her that the Russian president Vladimir Putin he didn’t respect her.

She replied, “Well, that’s because she’d rather have a puppet as President of the United States.”

This led to one of the most memorable moments of the final presidential debate of 2016, with Trump replying, “No puppet. Not a puppet. You are the puppet. No, you’re the puppet.”

Clinton has described that moment as a real revelation for Trump — and one that could happen again tonight if Harris gave him the go-ahead.
